Troubleshooting
If a problem arises while you are using the TV, please read this troubleshooting guide carefully before you ask to have the TV repaired. You may be able to fix it easily by yourself. For example, if the mains plug is disconnected from the mains outlet, or the TV aerial has problems, you may think there is a problem with the TV itself.
Important:
•This troubleshooting guide only covers problems whose causes are not easy to decide. If you have a question when you are operating a function, read the page(s) for that function carefully, not this troubleshooting guide.
•If you follow the advice in this troubleshooting guide without any success, unplug the mains plug and ask for your TV to be repaired. Do not attempt to repair the TV by yourself or to remove the rear cover of the TV.
If you cannot turn on the TV
•Is the mains plug connected to the mains outlet?
•Is the power lamp lit? If not, press the main power button.
No picture or no sound
•Have you chosen a TV channel with very poor reception? If so, the BLUE BACK function will be activated: the entire screen becomes blue, and the sound is muted. If you still want to view the TV channel, follow the description “BLUE BACK” on page 28 to try to change the BLUE BACK function setting to OFF.
•Have you set the speaker function to OFF? Follow the description “SPEAKER” on page 21 to check the speaker function setting.
Poor picture
•If noise (snow) totally blocks out the picture, there may be a problem with the aerial or aerial cable. Check the following to try to solve the problem:
−Have the TV and aerial been connected properly?
−Has the aerial cable been damaged?
−Is the aerial pointing in the right direction?
−Is the aerial itself faulty?
•If the TV or aerial suffers interference from other equipment, stripes or noise may appear in the picture. Move any equipment such as an amplifier, personal computer, or a hair drier, that can cause interference away from your TV. Or try moving the TV. If the aerial suffers interference from a radio tower or
•If the TV suffers interference from signals reflecting from mountains or buildings,
•Are your COLOUR SYSTEM settings correct? Follow the description “COLOUR SYSTEM” on page 20 to try a way to solve the trouble.
•Have the COLOUR and BRIGHT settings been adjusted properly? Follow the description “Picture adjustment” on page 18 to try to adjust them properly.
•Videotaping teletext is not recommended because it may not record correctly.
•When a white and bright still image (such as a white dress) is displayed on the screen, the white part may look as if it is coloured. This is unavoidable due to the nature of the picture tube itself, and not due to a TV failure. When the picture disappears from the screen, the unnatural colours will also disappear.
•When viewing images from commercially available video software products, or videos from videotapes which have been recorded improperly, the top of the image may be distorted. This is due to the condition of the video signal, and not because of malfunction.

Poor sound
•Have you adjusted BASS or TREBLE properly? If not, follow the description “Sound adjustment” on page 21.
•When TV channel reception is poor, it can be hard to hear the stereo or bilingual sound. In this case, follow the description “STEREO / I•II” on page 21 to hear the sound more easily by changing it to a mono sound.
If the TV does not respond to the remote control.
•Have the batteries of the remote control worn out? Follow the description “Putting batteries into the remote control” on page 4 and replace them with new batteries.
•Have you attempted to use the remote control from the sides or rear of the TV or from more than seven metres away from the TV? Use the remote control in the front of your TV or from less than seven metres away.
•When you want to change the volume of the headphones, follow the description “HEADPHONE” on page 22.
•When you are viewing a teletext programme, you cannot operate the menus. Press the bbutton to return to the ordinary TV programme, and then try operating the menus.
•If the TV will not respond suddenly, press the main power button on the TV and turn off the main power. Press the main power button again to turn on the TV. If the TV returns to a normal state, it is not a failure.
Other issues
•When the SLEEP TIMER function operates, the TV is
automatically turned off. If the TV is turned off suddenly, try to press the #(standby) button to turn on the TV once again. If the TV goes back to normal, there is no problem.
•When a wide screen signal (WSS) is included in the broadcast signal or the signal from an external device, or when the TV is receiving a control signal from an external device, the ZOOM
mode will change automatically. When you want to return to the previous ZOOM mode, press the c
button to choose the ZOOM mode again.
•If you bring a magnetised device such as a speaker near to your TV, the picture may be warped or unnatural colors may appear at the corners of the screen. In this case, keep the device from your TV. If speakers cause this to happen, use
•A picture may be tilted due to the earth’s own magnetic field. If so, use the “PICTURE TILT” on page 20 to correct the tilt.
•It takes a short time from the time an operation such as changing channels is performed until an image is displayed. This is not a malfunction. This is the time it takes for the image to stabilize before it can be displayed.
•The TV may make a crackling sound due to a sudden change in temperature. The picture or sound may be normal. If you hear crackling sounds frequently while you are viewing the TV, there may be other causes. As a precaution, ask your service technician to inspect it.
•Touching the screen may cause you to feel a slight electric shock due to its static electricity. This is unavoidable due to the construction of the picture tube. It is not a problem with the TV. You can rest assured that this static discharge is not harmful.
